A laminate for use in decorating a receptor surface (e.g., a window) comprising a piece of decorative sheet material with a layer of aggressive pressure sensitive adhesive on its rear surface and a release liner over that layer of adhesive; and a flexible, temporary support tape comprising a backing and a layer of repositionable pressure sensitive adhesive on a second surface of the backing. A longitudinally extending part of the layer of repositionable pressure sensitive adhesive of the support tape is adhered to a front surface of the decorative strip, and an elongate portion of the support tape projects transversely away from a first edge surface of the decorative sheet material. The repositionable pressure sensitive adhesive on that projecting portion of the support tape can be adhered to a receptor surface with the first release liner on the decorative sheet material laying along that receptor surface, and can be repositioned as needed to precisely position the decorative sheet material in a desired location. Once so positioned, the flexible backing can be bent along a longitudinally extending bend line along the first edge of the decorative sheet material to separate the decorative sheet material from the receptor surface so that the first release liner can be manually removed. The decorative sheet material can then be moved back into contact with the receptor surface so that its layer of aggressive pressure sensitive adhesive adheres the decorative sheet material against the receptor surface in the desired location, after which the temporary support tape can be peeled away.

The present invention relates to assemblies and methods used for applying adhesive coated decorative sheet material to substrates such as sheets of glass.
Several decorative sheet materials are known that can be adhered to substrates such as sheets of glass to decorate the substrate. Typically these materials have an outer major surface that is viewed to see the decorative aspect of the materials, a layer of aggressive pressure-sensitive adhesive selected to form strong bonds to glass on an opposite rear surface, and a low-adhesion release liner over the surface of the adhesive opposite the sheet material. One such decorative sheet material is a length of film that has grooves, vapor coating and/or other structure along its outer major surface so that the decorative film visually simulates decorative glass, such as glass with a single bevel, beveled edges, or with a central groove along its length (e.g., a V shaped groove), or with a leaded appearance, or with a textured surface, or visually simulates a glass related structure such as metal came (e.g., the pieces of optical film described in U.S. Pat. No. 5,840,407 issued Nov. 24, 1998). Tapes including a length of the type of optical film disclosed in U.S. Pat. No. 5,840,407 and a layer of aggressive pressure sensitive adhesive along a rear major surface protected by a release liner are commercially available as 3M™ Accentrim™ Tape, series B200 (V-groove tape) and series B100 (edge bevel tape), from 3M Company, St. Paul, Minn. Other such decorative sheet materials include the decorative birefringent multiplayer film available from Minnesota Mining and Manufacturing Company, St. Paul, Minn., under the trade designation “Radiant Light Film” that is described in U.S. Pat. No. 5,882,774; or the vinyl films also available from Minnesota Mining and Manufacturing Company, that can be applied to glass panes to form graphics that appear to have been etched or sand-blasted into the glass at a fraction of the cost of actual etching or sand blasting. These vinyl films, typically plasticized poly(vinyl chloride), are marketed as Scotchcal™ Series 7725 special effects films. Among these, Scotchcal™ 7725-314 Dusted Crystal Film gives the appearance of etched glass, and Scotchcal™ 7725-324 Frosted Crystal Film gives the decorative appearance of sand-blasted glass.
Applying such decorative sheet materials to a substrate in a desired location can be difficult because of the aggressive nature of the adhesive on the sheet materials. Once that adhesive contacts a dry substrate such as a glass surface it is difficult if not impossible to reposition. Thus those applying the decorative materials face the challenge of making an initial contact between the flexible decorative sheet materials and the substrate with the decorative sheet materials at a precise predetermined position, which challenge can not always be met, particularly by persons with little experience in applying the sheet materials.
Various approaches have been developed for applying such decorative sheet materials to substrates with the sheet materials at desired predetermined locations relative to each other and along the substrate.
U.S. Pat. No. 5,665,446 describes a method for applying aggressive pressure-sensitive adhesive coated decorative sheet materials or graphics to a substrate (e.g., a sheet of glass) using a laminate comprising a polymeric cover sheet and a layer of pressure-sensitive adhesive adhered to one surface of the cover sheet with the cover sheet and layer of pressure-sensitive adhesive being vented. Generally that method includes the steps of (1) adhering surfaces of the graphics opposite their layers of pressure-sensitive adhesive to the layer of pressure-sensitive adhesive on the laminate so that they will have precise relative positions; (2) using a solution to wet the graphics, the laminate and the substrate; (3) placing the graphics adhered to the layer of pressure-sensitive adhesive on the laminate at a desired location on the substrate; (4) sliding the wet laminate and graphics along the wet substrate as needed to obtain a desired position; (5) pressing out air and water from between the substrate and the graphics adhered to the layer of pressure-sensitive adhesive on the laminate; (6) allowing the solution to dry; and (7) removing the laminate to leave the graphics firmly adhered to the substrate.
U.S. Pat. No. 6,805,932, describes a method for persons such as homeowners to apply to a substrate (e.g., a sheet of glass) decorative designs made using separate pieces of optical film of the type described in U.S. Pat. No. 5,840,407, each of which pieces has a layer of adhesive along one surface, and an opposite outer major structured surface described above. Generally, that method comprises the steps of(1) providing a kit including a layer of pre-mask material that is at least translucent comprising a cover sheet with a layer of removable adhesive (e.g., pressure-sensitive adhesive) firmly adhered to one surface; a predetermined printed design; and pieces of optical film having peripheral shapes that correspond to parts of the printed design, each of which pieces of optical film have a layer of adhesive (e.g., pressure-sensitive adhesive) along one surface, and an opposite outer major surface (e.g., a grooved and/or vapor coated surface) so that the pieces visually simulate decorative structures; (2) placing the pieces of optical film over portions of the design corresponding to their shapes with the outer major surfaces of the pieces of film along a common plane; (3) adhering the layer of adhesive on the layer of pre-mask material to the outer major surfaces of the pieces of film; (4) placing the pieces of optical film adhered to the layer of adhesive on the layer of pre-mask material at a desired location on the substrate, (5) pressing the layer of pre-mask material and thereby the pieces of optical Win adhered to the layer of pre-mask material against the substrate, during which pressing step, the layer of pro-mask material protects the outer major surfaces of the pieces of film from damage; and (6) removing the layer of pre-mask material to leave the pieces of optical film adhered to the substrate in the predetermined design. Preferably the layer of pro-mask material is or has been made transmissive of moisture vapor (e.g., a layer of pre-mask material that is vented as described in U.S. Pat. No. 5,665,446), a wetting liquid is used to wet the pieces of optical film, the layer of pre-mask material and the substrate prior to the step of placing the pieces of optical film adhered to the layer of adhesive on the layer of pry-mask material at a desired location on the substrate, which wetting liquid allows sliding the wet pieces of optical film and layer of pre-rnask material along the wet substrate as needed to obtain a desired position for the pieces of optical film, and is allowed to dry between the pressing step and the step of removing the layer of pre-mask material.
U.S. Pat. No. 6,571,849, describes using a computer operated machine to form and accurately apply to a substrate (e.g., a sheet of glass in a window, door, or mirror) decorative designs made of decorative sheet material in strips, such as strips of the optical film described in U.S. Pat. No. 5,840,407.
U.S. Pat. No. 6,773,537, describes modifying the machine described in U.S. Pat. No. 6,571,849 and using it to form a laminate that persons such as homeowners can use to accurately apply to a substrate (e.g., a sheet of glass) decorative designs made of strips of decorative sheet material of the types described above. Generally the tape applicator forms the strips of decorative sheet material with different predetermined lengths and end shapes from a supply length of the strip of decorative material and either (1) adheres the coatings of adhesive on them to a release liner in a predetermined pattern, after which a layer of removable adhesive on a layer of pre-mask material can be adhered over the outer major surfaces of the display lengths of decorative film tape adhered to the release liner and to the release liner around the display lengths of decorative film tape to make the laminates; or (2) adheres their front surfaces to the layer of removable adhesive on the layer of pre-mask material in a predetermined pattern, after which the release liner can be applied over the coatings of adhesive on them to make the laminate. That laminate can then be used to apply the strips of decorative material to a substrate in the maimer described above with reference to U.S. Pat. No. 5,665,446.
While all of the approaches described above are useful for applying decorative materials to substrates, the search is ongoing for other useful structures and methods for doing so.
The present invention provides a laminate and a method using that laminate by which a person can quickly and accurately apply decorative material coated with aggressive pressure sensitive adhesive to a substrate in a desired pattern that for some types of applications is simpler, and more versatile than the prior art approaches described above.
According to the present invention there is provided a laminate for use in decorating a receptor surface such as the surface of a window or mirror. That laminate comprises an piece of decorative sheet material with a generally straight first edge surface, a layer of aggressive pressure sensitive adhesive on its rear surface, and a first release liner over a surface of that layer of adhesive opposite the decorative sheet material; and a flexible, temporary support tape comprising a backing and a layer of repositionable pressure sensitive adhesive on a second surface of the backing. A part of the layer of repositionable pressure sensitive adhesive adjacent a second edge surface of the backing is adhered to a front surface of the decorative material with a portion of the support tape projecting away from the first edge surface of the decorative strip. The repositionable pressure sensitive adhesive on that projecting portion of the support tape can be adhered to a receptor surface with the release liner on the decorative material laying along that receptor surface, and can be repositioned as needed to precisely position the decorative strip in a desired location along that receptor surface. Once so positioned, the flexible backing can be bent along a bend line along the first edge of the decorative material to separate the decorative material from the receptor surface so that the release liner can be manually removed. The layer of aggressive pressure sensitive adhesive on the decorative material can then be moved into contact with the receptor surface to adhere the decorative material against the receptor surface in the desired location, after which the temporary support tape can be peeled away from both the receptor surface and the decorative material.
The present invention will be further described with reference to the accompanying drawing wherein like reference numerals refer to like parts in the several views, and wherein:
Referring now to
As can be seen in
The elongate strip of decorative sheet material 14 can be any sheet material that provides decoration for a substrate including (but not limited to) the film that has grooves, vapor coating and/or other structure along its outer major surface so that the decorative sheet material or film visually simulates decorative glass, such as glass with a single bevel, beveled edges, or with a central groove along its length (e.g., a V shaped groove), or with a leaded appearance, or with a textured surface, or visually simulates a glass related structure such as metal came (e.g., the pieces of optical film described in U.S. Pat. No. 5,840,407 issued Nov. 24, 1998, the content whereof is hereby incorporated herein by reference). Tapes including a length of the type of optical film disclosed in U.S. Pat. No. 5,840,407 and a layer of aggressive pressure sensitive adhesive along a rear major surface protected by a release liner are commercially available as 3M™ Accentrim™ Tape, series B200 (V-groove tape) and series B100 (edge bevel tape), from 3M Company, St. Paul, Minn. Other such decorative sheet materials that can be used include the decorative birefringent multiplayer film available from Minnesota Mining and Manufacturing Company, St. Paul, Minn., under the trade designation “Radiant Light Film” that is described in U.S. Pat. No. 5,882,774 (the content whereof is hereby incorporated herein by reference); or the vinyl films also available from Minnesota Mining and Manufacturing Company, that can be applied to glass panes to form graphics that appear to have been etched or sand-blasted into the glass at a fraction of the cost of actual etching or sand blasting. These vinyl films, typically plasticized poly(vinyl chloride), are marketed as Scotchcal (trade mark) Series 7725 special effects films. Among these, Scotchcal (trade mark) 7725-314 Dusted Crystal Film gives the appearance of etched glass, and Scotchcal (trade mark) 7725-324 Frosted Crystal Film gives the decorative appearance of sand-blasted glass.
The support tape 26 can be any tape including the layer 34 of repositionable adhesive and the backing 28 which flexes easily and does not stretch when the decorative sheet material 14 is moved away from and then back into contact with the receptor surface 12 so that the decorative sheet material can be returned to its desired position after the first release liner 24 is removed. Suitable support tapes 26 include masking tapes with nonstretchable paper-like backings, particularly including the masking tape commercially available from 3M Company, St. Paul, Minn., under the trade designation 2090 Longmask™ which has low adhesion to glass.
The support tape 26 can be applied to the decorative sheet material 14 at the location at which the decorative sheet material 14 is to be adhered to a substrate either manually or to a roll of the support tape by using a laminating device such as the device described in U.S. Pat. No. 4,990,244, Heil et al., the content whereof is hereby incorporated herein by reference. Alternatively, the support tape 26 could be applied to the decorative sheet material 14 at a location other than that at which the decorative sheet material 14 is to be adhered to a substrate, in which case, as is illustrated in
The second edge surface of the decorative sheet material can be straight and parallel to its first edge surface as is the second edge surface 20 of the sheet material 14 illustrated in
Also, as shown on a laminate 60 illustrated in
When applying elongate strips of decorative sheet material such as the pieces or strips of decorative sheet material 14 or 14a to a substrate it is often desirable to form new ends on the strips at certain angles with respect to edge surfaces 18, 20; or 18a using a sharp cutting implement (e.g., a single edged razor blade or knife). Making cuts at those angles can be facilitated with a cutting guide block 70 of the type illustrated in
The present invention has now been described with reference to several embodiments and modifications thereof. It will be apparent to those skilled in the art that many changes can be made in the embodiments described without departing from the scope of the present invention. For example, the guide block could have more than two sides disposed other than parallel to each other to provide any number of desired cutting guide angles. Thus, the scope of the present invention should not be limited to the structures and methods described in this application, but only by the structures and methods described by the language of the claims and the equivalents thereof.
